TEL-21830 Digital Spectrophotometer

This digital spectrophotometer is used for quantitative investigations of emission and absorption spectra and transmission curves, and for measurements related to calorimetry and chemical kinetics. Based on the Czerny-Turner principle, this device permits simultaneous, real-time recording and analysis of the entire visible range from 380 nm - 830 nm in conjunction with the user-friendly measurement and evaluation software. Light is recorded by means of an optical fiber and projected on a CCD detector via two mirrors and a reflection grating.

The TEL-21830 Digital Spectrophotometer includes an absorption module with cell and slide holders for disposable cells and color filters, a software program and various connecting cables.
